Renegade Krasis was already known. If that's the last mythic ... it's pretty bad. Slaughter Games seems strictly better. Skylasher, though, will see lots of play. Too bad there aren't a lot of blue creatures that see play.

Really like the Scion! Getting a pair of them for my Séance deck! Also very good with the */* token as it gives you three creatures.
The Skylasher is an odd one, but hey, more control hosing! Would have been amazing if Delver was still a thing, but he is in older formats, so who knows?
The mythic is... Too similar to Slaughter Games...

Wow that skylasher has a lot of abilities on it with a lot hate on blue. The Dimir Mythic seems ok maybe constructed playable as you can remove multiple possible threats but if they haven't drawn those threats yet it's pretty underwhelming in my opinion. How did he/she even have access to a fat pack this early?

Scion will see play just like Blade Splicer saw play ... it's a way to get a lot of bodies out for relatively cheap (though not as cheap as Splicer). Even better if you have a Beast Token or Wurm Token (or Voice of Resurgence elemental) on the battlefield. Too bad it's not blinkable at all.

The big difference being that with slaughter Games, unless you Gitaxian Probe them, you're guessing... Here, they reveal their hand, then you choose.

This is of course strong against a lot of blue stuff (kill counterspells, Snapcasters, etc.) but exactly those decks will have strong countermeasures. If this had the uncounterable clause like Slaughter Games, it would be quite ridiculous.

I guess the Dimir fans will continue complaining...

Far and Away their field during their end step, bouncing a Thrag or something else impressive, saccing another of their creatures. During your turn drop a land, tap six so x=2 for Reap. You will, for sure, hit their Thrag. Plus you get to Lobotomize something else.

Slaughter Games you know their deck and might hit a card out of hand, here you're Duressing them and then insulting them on top of it. Which is better varies by circumstances.
